If that does not help, you can set the SQLCommandtimeout to your desired time, I mean to say you can calculate the time it takes to max execute your query and set that time as timeout.You can do that as below

SQLComm.CommandTimeout = x

replace here SQLComm by your object of sqlcommand, and X by the integer value(i.e secs).

Hope it helps,

Thanks and Regard
